2.4 Combustion Air Control
The Combustion Air Control is a patented mechanism (Patent
No: US 7,325,541 B2) that regulates the air flow into the
firebox based on the temperature of the unit. It is located on
the top of the firebox, at the front center of the unit (see Figure
2-1). The combustion air control of the FUSION has two
components: the Activator and the Burn Rate Selector. The
left combustion control lever is the Activator. When starting a
fire or adding a new load of wood, the Activator must be
pushed in to allow a primary source of air to enter the firebox.
The Activator will retract automatically with heat. The right
combustion control lever is the Burn Rate Selector. The Burn
Rate Selector can slide sideways to achieve different burn
rates. When the Burn Rate Selector is positioned to the left, a
maximum burn rate is achieved and when it is positioned to
the right, a minimum burn rate is set.
WARNING: Never manipulate the Combustion Air Control
with bare hands as it gets hot when the FUSION is in
operation. Use the Cold Hand Key (see Section 2.6) to
adjust the Combustion Air Control.
2.5 Baffle Secondary Burn Technology
The baffle system(18FN1150 or 24FN1150)of the FUSION insert is located
within the upper portion of the firebox (Figure 2-2) and is fastened by 6 bolts
(3/8 Hex). SUPREME baffle systems are constructed out a specific grade
of stainless steel capable of withstanding high-temperature conditions. The
secondary combustion air is drawn into the baffle system, pre-heated, and
distributed below the lower plate, allowing for a cluster of small flames
flowing downwards. This effect is more visible in the minimum burn rates.
For optimal performance, it is recommended to clean any creosote build-up
on the lower plate of the baffle system.
2.6 Cold Hand Key
The Cold Hand Key (Figure 2-3) is an accessory that comes standard with the FUSION
insert. The Cold Hand Key is a tool used to manipulate the Combustion Air Control Levers
when it is hot.
2.7 Chimney Sweeping Cap
The chimney sweeping cap (Figure 2-4) found at the baffle of the FUSION
allows easy access for chimney sweeping without having to remove any
components of the firebox.
WARNING: The chimney sweeping cap should be blocking the access to
the chimney at all times during combustion. A chimney sweeping cap that
is not blocking the baffle hole during combustion is a safety hazard, will
overheat the fireplace and void the warranty.
